Engineering Bereitschaft as an enabler for concurrent engineering

Industrial companies observe a general trend towards more customised products and shorter product life cycles. Furthermore, the market demands shorter lead-time and high-quality products at a competitive price. Concurrent Engineering addresses these challenges. Product modelling is a key aspect of the Concurrent Engineering literature. One problem with the product modelling literature is that it tends to assume that product development always is revolutionary. Very often product development is evolutionary and it means that product modelling should have a major emphasis on reuse. In this paper it is suggested that industrial companies should develop an engineering development Bereitschaft (preparatory engineering knowledge) as an approach to Concurrent Engineering and product modelling. To develop such an engineering development Bereitschaft, a company must develop company generic product models. This paper will describe experience from a shipyard where an object-oriented product model of a double hull supertanker and a product configurator prototype has been developed. Configuration of the steel structures in a ship and the succeeding productivity evaluation can in that way be done within a week. Such a fast cycle time allows for multiple iterations in search of a "good" design. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.
